What Our Customers Say
EXCELLENT Based on 68 reviews Benjamin T2025-05-02Trustindex verifies that the original source of the review is Google. Paul from ARCS Sydney falsely accused a seller of dropshipping, even though the item was shipped locally from Melbourne and tracking clearly showed it was delivered by Australia Post to his address in Emu Heights, NSW. Despite being provided with full tracking evidence and clear communication, he continued to insist the item was never sent and left misleading negative feedback. When approached for a resolution, he was extremely rude, dismissive, and difficult to communicate with. This review is to caution others about the uncooperative and disrespectful manner experienced in dealing with this individual. Ed Neeves2025-03-28Trustindex verifies that the original source of the review is Google. I read a load of reviews about the team at ARCS and was really pleased to hear about people’s experiences. Not only that but they were relatively local to me too! The experience completely lived up to my expectations, with the feeling of a family member helping you out, the quality of installation that feeds my OCD and a professionalism that is top notch. Went from a 3 node mesh wifi that would constantly drop for no reason to a 2 Access Point system with hard wired TV’s that is pretty much maximum speed that our plan allows. Really looking forward to never thinking about my WIFI again!!! If you want the same I can’t recommend ARCS enough. Eddie Rijk2025-02-20Trustindex verifies that the original source of the review is Google. We were having ongoing issues with our internet service at home. Telstra were no help & said there wasn’t any fault at their end. We contacted Paul & he came very quickly. He tested everything and proved that the fault was caused at Telstra’s end. Paul explained everything to us & even made a video clip explaining the problems, so we can show the Telstra tech when they finally turn up. If you are having technical issues, I highly recommend Paul. Thanks for your help Paul. I would have given you more than 5 stars if I could😀 Kent “Doug” Douglas2025-02-17Trustindex verifies that the original source of the review is Google. Paul at ARCS came to inspect the "stage 1" work of NBN connecting fibre to premises and found multiple issues with the installation. He was able to confirm the existing premise wiring was not compliant with the "stage 2" FTTP installation. I engaged him to lay a new fibre connection to the house in order to make the future NBN work a seamless transition and he exceeded expectations. He was able to do the work utilising existing infrastructure without any new holes or damage and then tidied up the woeful work the NBN contractprs had performed when installing the new lead in fibre. He also managed to repair the existing connection NBN damaged as we had been without internet for nearly a week. I could not recommend him highly enough and will certainly utilise his skill for any future cabling projects. Peterpetrum2024-11-28Trustindex verifies that the original source of the review is Google. We highly recommend Paul from ARCS. We were having problems with our internet connection with Vodafone. Vodafone said that it was all OK as far as the NBN node, but the problem was with the wiring from there to the house. We found Paul and he arrived when arranged and within minutes had identified two issues. One he fixed immediately, with an instant increase in speed, the other was in a junction box on the Telstra line that was inaccessible. He checked and found that NBN fibre would soon be available in our area and provided all the information we needed to arrange for NBN to link us up. Paul is affable, friendly and obviously very experienced. If you live in the Penrith/Blue Mountains area, he is the person to go to. marnie cullens2024-02-28Trustindex verifies that the original source of the review is Google. Very friendly service, Paul was knowledgeable and resolved our issues quickly. Would definitely recommend for any cabling you require. Fraser Leishman2023-09-20Trustindex verifies that the original source of the review is Google. Thank you Paul for fixing fibre to home connection. It is working like a dream. Ash Wheatley2023-09-02Trustindex verifies that the original source of the review is Google. We broke our fibre optic cable and Paul was very quick to come round and fix up the issue for us. Great service, would highly recommend. Andrew Krisenthal2023-07-03Trustindex verifies that the original source of the review is Google. Brilliant experience and service all around. Initially had Paul come out to run some upgraded fibre through my house. On time, professional, navigated issues and great install. Subsequently had some issues with NBN tech installing FTTP. Paul took a phone call, tried talking to the NBN tech for me during the appointment and advocated for me and what was happening. When NBN continued to refuse what they should have done Paul offered to come out that afternoon without a booking and for no charge to rectify the work and had me up and running in 3 minutes. A fantastic company, an amazing bloke and high quality work. Would recommend to anyone without hesitation. The MeataXe2023-05-24Trustindex verifies that the original source of the review is Google. Amazing service & priced amazingly Would recommend to everyone
